I'm having an issue with converting between p-adic and rational numbers. Specifically, there are certain p-adic numbers that I cannot convert to rationals. As an example, if 1+7^3+O(7^5) is a 7-adic integer with capped relative precision 5, I cannot convert it to a rational. I get the error "ValueError: Rational reconstruction of 344 (mod 16807) does not exist."
More generally, it seems that if the precision of the p-adic number is O(p^n), and the p-adic number includes powers of p greater than n/2, the number cannot be converted to a rational. Any info is appreciated.
